the only drawback with the pvc feeder is that the whole thing could be eaten up in one night b/c there is nothing keeping the deer from feeding until it is gone, therefore you better be around often to fill it back up, the deer will also realize that there is corn there all day long and will just go at night to feed when they feel safer, we used to use these and also had a terrible coon and squirrel problem with them. What we now use is a homemade feeder similar to ones sold at stores for $300, all we did was take a 55 gallon drum, bolt 3 steel legs into the sides about 8 feet long, cut a hole in the bottom of the barrel and attach an electric broadcaster to it that dumps out corn twice a day, they are at cabelas for about 30 bucks, it can hold about 300-400 lbs of corn and works great, once the feeder goes off the deer come in like its dinner time, we have 2 of these on our land and love them, only costs about $50 for it, instead of several hundred at the store to buy a premade one
